Original application led March 27, 1916, Serial No. 86,990. Divided and this application filed December 14, 1916. Serial No. 136,901.

To all 'whom may concer/n:

Be it known that I, FRANK H. Mamans, a citizen of the United States, residing at Cincinnati, in the county ozt Hamilton and State oi Chio, have invented certain new and useful Improvements in Flushing- Valves, of which the following is a specification.

My invention relates to flushing valves, especially for water-closets for outdoor use or otherwise where freezing of water in the valve and connections is to be guarded against. lts object is to simplify devices ot this character and to render them more reliable and less liable to derangement and leakage.

My invention consists in the combination of parts and in the details of construction and arrangement of parts as will herein be more fully described and claimed.

1n the drawing:

Figure 1 is a plan view of a device embodying` my invention;

Fig. 2 is a view partly in elevation and partly in vertical section on a plane correspending` to the line 2 2 of Fig. 2, parts being` broken away for lack of space;

Fig. 3 is an inverted plan view of the device with the bottom plug removed to reveal the interior construction; and

Fig. d is a cross-section of the same, on a plane corresponding to the line 4 1 of Fig. 2.

My invention, as disclosed and claimed herein, was originally disclosed and claimed in my co-pending application Serial No. 86,990, iiled March 27, 1916, of which this present application is a division.

As shown in the drawing and as l prefer to construct my invention, the valve body 1 is in the form of a longl upright cylinder with a chamber 2 in its lower end closed by a bottom plug 3 and having the pipe l leading into its side from the water main or other source of supply ot water under pressure. The upper main part 5 of the body 1 is of interior diameter lessthan that of the chamber 2, with its lower end part where it joins the chamber' 2 intcriorly threaded to receive the exteriorly threaded valve-seat 6, increasing in interior diameter upwardly to form the valve-seat, and with notches 7 in its bottom to receive the Spanner. Above this ring` 6, the valve-plug` 8 slides up and down in the valve body 1, being` but slightly less exterior diameter than the interior diameter oi' the body 1, and thus guided to freely enter its lower tapered end part 8 in the valve-seat.

LeadingI from one side ot this main part of the valve-body 1, preferably just above the upper end of the valve-seat ring` 6, is a side port 9, which passes up the outside of the valve-body 1 and then leads into the interior of said body 1 above the highest point to which the upper end of the plugl S will tra-vel. From the top of the valve-body 1 leads the casing tube 10; and the stem 11 has its lower end screwed into the upper end of the valve-plug 6 and extends up through the casing tube 10.

rllhe valve-body 1 also has a small drain chamber 12 at the bottom of the side port 9, with which it communicates through a very small hole 13. From this drain chamber 12 there leads a drain pipe 14, which may connect with the soil pipe of the water closet, not herein shown. To drain the part of the valve-body 1 above the valvesplug 8, a-small hole 13 may be provided in the side, leadinginto the side port 9.

lt will be understood that the entire valve-body 1 and its connections are buried in the ground below the frost line as indicated in Fig. 2; the casingtube 10 and the stem 11 'therein extending` up past the surtace of the ground. On the lupper end of the casing` tube 10 screwed the connection head 15, having' a stul'ling-box 1G in its top, through which the stem 11 projects without allowing' leakage. rlhe head 15 has a side extension, and to this is connected the 'Hushinp; pipe 17, leading' to the bowl 18. The upper end part of the stem 11 extends between the members oi the :toi-lr 19 projecting rearwardly Jfrom the seat 20, with a nut 21 to engage its lower side with the fork 19, and held on by a lock-nut 2,2, cappingl the upper end of the stem.

its long as the scat 2O is raised, the valveplug S is wedged in its seat in the ring 6; but lowering' 'the seat 20 raises the plugl 8 as indicated by the dotted lines in Fig. 2; allowing the water under pressure to pass `from the pipe li, up past the valve-seat. through the. side port 9, the upper part of the body 1, the casing' tube 10, connection head 15, and pipe 17, to the bowl 1S. The flushing continuos all the time the scat is lowered, and the plus; descends when the seat 2O is raised, or may be so heavy as to slowly raise the. seat 20 by descending slowly aga-inst the water pressure when the weight of the person is removed from the seat. Thus, the plug may be amply heavy for cutting oil' the flow of water by wedging in its valve-seat, and thereafter resisting the water pressure suiliciently to remain closed until raised again by depression of the seat 20.

r As is indicated, the valve is here made. of

' to hold securely in the valve-seat.

a minimum area, so that the eiiiect of the hydraulic pressure is slight, and the taper of the plug and ilaring of the valve-seat are made of such length as to enable the plug It will be understood that the plug may be of ample length to have the weight required to suficiently overbalance the seat 20, and resist the water pressure. The valve-seat ring 16 is renewed when worn; access being had through the bottom o the chamber 2 after removing the plug 3. It is, of course, necessary to excavate to reach these parts. All other parts that need to be reached, such as the stuliing box 16, are above the surface of the ground. At the same time, upon closure of the valve, all parts above the frost line are well drained so that the device is not rendered inoperative during extremely cold weather.

It will be seen that the parts of my improved iiushing valve are few and have a very simple relation to each other; all except the packing in the stuiiing box 16 may be of metal, eliminating the use of rubber or other soft material in the. valve itself. The ring 6 may be of such ample dimensions that the ciliciency of the valve-seat will not be impaired even after very considerable wear thereon, so that excavation will not be necessary for a very considerable period ot' time. The elimination of all springs is also a great advantage.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

1. ln a flushing valve, in combination with a raisable and depressible seat element, a body having a middle vertically elongated main part with straight smooth interior walls, and having an inlet passage below and an outlet passage above said main part, a

valve seat of interior dimeter increasing upwardly, between said main part and said inlet passage, a plug fitting said interior walls of said main part and slidable up and down therein, with a downwardly tapering part fitting in said valve seat, an operative connection extending through the upper part of said body from said plug to said seat element, whereby said plug and said seat element are so related that either one is raised as the other is depressed, said plug being of such length and thickness that it overbalances said seat element against the pressure of water from said inlet passage, said body also having a side port from the interior ofV said main part immediately above said valve seat to the interior of said'main part above the highest point reached by the upper end of said plug when raised.

2. In a flushing valve, in combination with a raisable and depressible seat element, a
